Not in last year's.  I sat in it for a couple of hours three weeks ago, and 
thoroughly investigated _all_ of the technology.  The front and rear suspension 
adjustments were two 3" diameter knobs on the left of the central control 
panel, inconveniently positioned for me but perhaps OK for Biela, who is huge.  
They sure looked like differential flow valves.

Well, the old system would have been inconvenient to operate during a race.  
The total suspension travel, BTW, is only three centimetres or so, and more 
than 50% is tyre elasticity.  The "suspension" as such has a travel of not much 
over a centimetre.
